Some rotary wing aircraft are designed to stop the rotor for forward flight so that it then acts as a fixed wing.

Additional fixed wings may also be provided to ...

All three classes have been studied for use as lifting rotors and several variations have been flown on full-size aircraft, although only the vertical-axis rotary wing has become widespread on rotorcraft such as the helicopter. Some types provide lift at zero forward airspeed, allowing for vertical takeoff and landing (VTOL), as in the helicopter.
Some trees (for example maple trees) have seeds that have wing-like structures that enable the seed to spin to the ground in autorotation, which helps the seeds to disseminate over a wider area. The most common use of autorotation in helicopters is to safely land the aircraft in the event of an engine failure or tail-rotor failure.
West Coast Swing is a slotted dance, which means that the steps of the dance are confined to an imaginary "slot" on the dance floor. For West Coast Swing, the slot is a long, thin, rectangular area whose length depends on the tempo of the music – it can be eight or nine feet long for slower songs, but will be shorter for faster music.
